Title: Magneto-optical recording device
Inventor: HORIGOME HIDEYOSHI
IPC: G11B11/105
Filed: 1994-08-08
Abstract: PURPOSE:Not to form a noise-up region and to perform a good high density recording. CONSTITUTION:An oscillation circuit 19 supplies an oscillating signal to a coil 7A of an electromagnet 7 which applies a magnetic field to a magneto-optical recording medium 1 based on a prescribed clock signal and the direction of the magnetic field is periodically reversed. The magnetic field has a peak value which is larger than the strength required to reverse the magnetization direction of the medium 1. Information signals to be recorded to the medium 1 are supplied to an optical modulation circuit 22 and an optical head section 4 is driven so that a laser beam LB is pulse emitted in accordance with the signal levels of the information signals and the oscillation signals. The circuit 22 stops the driving of the section 4 unless the magnetic field strength have enough strength to reverse the magnetization direction of the medium 1 during the time in that the magnetic field generated by the electromagnet 7 reverses its direction.

Title: Method of detecting nonmetallic inclusion in high carbon steel
Inventor: KIDO ATSUSHI
IPC: G01N29/30
Filed: 1989-08-09
Abstract: PURPOSE:To highly accurately detect micro nonmetallic inclusions in high carbon steel by a method wherein a sample is rolled with a specific reduction ratio as a pretreatment for flaw detection and subjected to quenching or spheroidizing. CONSTITUTION:When nonmetallic inclusions are to be detected by means of supersonic flaw detection, a sample is rolled with a reduction ratio of 20 to 200 as a pretreatment for flaw detection. The reduction ratio is for discriminating micro nonmetallic inclusions from a rough flaw and for preventing an excessive deformation of the nonmetallic inclusions while a reduction ratio of 30 to 60 is more preferable and a ratio of 40 to 50 is especially preferable. In a quenching heat treatment, tempering is preferable after quenching to prevent quenching cracks from occurring. Then a point focusing probe with a frequency of 10 to 30MHz is used as an ultrasonic probe to perform ultrasonic flaw detection. Thus loose structures of a steel material can be press-welded as well as made in an appropriate size for detecting the size of the nonmetallic inclusions so that confusion of the loose structures and the nonmetallic inclusions can be avoided and micro nonmetallic inclusions can be detected with detection accuracy improved.

Title: Material for ornamentation
Inventor: OKAMOTO RIYUUZOU
IPC: B23K1/19
Filed: 1983-11-04
Abstract: PURPOSE:To prevent deterioration in an ornamentation effect on account of rusting occurring in the contact potential difference between different metals in the stage of producing a material for ornamentation joined with the different metals by providing an insulating layer to the joint part in contact with the corrosive environment of the outside part. CONSTITUTION:Ornamental parts such as external parts for a portable watch, etc. are manufactured by the combination of gold and a metal such as stainless steel having the color tone different from the color tone of gold to provide the ornamental effect thereof. The stainless steel as the metal on the anode side is rusted owing to a large difference in the contact potential between both metals and the decreased ornamental effect resulted in this case. A long groove having 0.5mm. depth is formed to the stainless steel 2 and a transparent SiO2 insulating layer 4 is calcined by 0.2mm. over the entire outside circumferential part thereof. Gold 1 is then polished by sandpaper to the same shape adapted to the shape of the groove. Such gold 1 is brazed to the groove by 18K gold solder 3. The gold and the stainless steel in the part facing the outside world of corrosive environment are insulated by the SiO2 insulating layer and therefore the decrease in the ornamental effect by rusting is obviated.

IPC: F02P17/12
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To improve ionic current detecting accuracy by shortening the remanent magnetism vibrating time just after spark discharge of an ignition plug. SOLUTION: Since the stray capacity 43 exists on a high voltage cord 42 for connecting a secondary coil 26 of an ignition coil 21 and an ignition plug 27 to each other and the secondary coil 26 of the ignition coil 21, an LCR resonance circuit is formed of the stray capacity 43, the secondary coil 26 and an ionic current detecting resistor 31, and resonance waveform (remanent magnetic noise) is generated by remanent magnetic energy on the secondary side of the ignition coil 26 just after spark discharge of the ignition plug 27. Q of the LCR resonance circuit is so constituted as to be in the range of 0.5 to 3.0, preferably, in the range of 0.6 to 2.0 in order to decrease the effect of the remanent magnetic noise. Therefore, the remanent magnetism vibrating time becomes the target value (about 0.8 ms) or less, and the remanent magnetic noise can be quickly damped.
